Penicillus

Penicillus capitatus

Lamarck 1813

Neptune's Shaving Brush

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: West Indies, Florida, and Bermuda.

Natural Environment: Inhabits shallow protected lagoon sandy areas.

Aquarium Suitability: Prefers sandy bottom areas and intense light. Its upright stalks are short lived however, maybe lasting only a few weeks. Yet new growths will occur within a short distance of the main stalk via runners from the disintegrating central stalk. May grow up to a few inches per day and is a good water quality indicator. Requires moderately high alkalinity and calcium levels.

Taxonomy:

    Kingdom: Plantae

    Phylum: Chlorophyta

    Class: Ulvophyceae

    Order: Bryopsidales

    Family: Udoteaceae

    Genus: Penicillus

FYI: Referred to as Neptune's Shaving Brush because it has a thick stalk crowned with a tuft of green to white filaments.
